Studies of donor CAR T cells placed on hold
The US Food and Drug Administration (FDA) has placed a clinical hold on both phase 1 studies of UCART123, a universal (allogeneic) chimeric antigen receptor (CAR) T-cell therapy targeting CD123.
One study was designed for patients with acute myeloid leukemia (AML), and the other was designed for patients with blastic plasmacytoid dendritic cell neoplasm (BPDCN).
The clinical hold is due to the death of the first patient treated in the BPDCN trial.
The hold means no new subjects can be enrolled in either trial, and there can be no further dosing of subjects who are already enrolled.
BPDCN patient
The first patient treated in the BPDCN trial was a 78-year-old male who had received 1 prior therapy. He presented with relapsed/refractory BPDCN with 30% blasts in his bone marrow and cutaneous lesions (biopsy-proven BPDCN) at baseline.
The patient first received pre-conditioning with fludarabine (30 mg/m²/day for 4 days) and cyclophosphamide (1 g/m²/day for 3 days).
On August 16, 2017 (Day 0), the patient received UCART123 at 6.25 x 105 cells/kg, the first dose level explored in the protocol, without complication.
By Day 5, the patient had developed grade 2 cytokine release syndrome (CRS) and a grade 3 lung infection, which improved after a first dose of tocilizumab and the administration of broad-spectrum, intravenous antibiotics.
On Day 8, the patient was found to have more severe CRS (ultimately grade 5) and grade 4 capillary leak syndrome. Despite receiving treatment in keeping with CRS management, including the administration of corticosteroids and tociluzumab as well as intensive care unit support, the patient died on Day 9.
AML patient
The first patient treated in the AML study experienced similar adverse effects as the BPDCN patient but is still alive.
The AML patient was a 58-year-old woman with 84% blasts in her bone marrow at baseline.
On June 27, 2017 (Day 0), the patient received the same pre-conditioning regimen and the same dose of UCART123 as the BPDCN patient, without complication.
By Day 8, the AML patient had developed grade 2 CRS. This worsened to grade 3 on Day 9 and resolved on Day 11 with treatment in the intensive care unit.
The patient also experienced grade 4 capillary leak syndrome on Day 9 that resolved on Day 12.
Next steps
The data safety monitoring board for these trials met on August 28 and recommended lowering the dose of UCART123 to 6.25 x 104 cells/kg in both studies and capping cyclophosphamide to a total dose of 4 g over 3 days.
Cellectis, the company developing UCART123, said it is working with study investigators and the FDA to resume both trials with an amended protocol that includes these dose adjustments.

FDA grants orphan designation to product for CMV
The US Food and Drug Administration (FDA) has granted orphan drug designation to ATA230 for the treatment of cytomegalovirus (CMV) viremia and disease in immunocompromised patients.
ATA230 is an allogeneic, cytotoxic T-lymphocyte (CTL) product targeting antigens expressed by CMV.
The product is under investigation in phase 2 trials of patients with CMV viremia and disease who are refractory or resistant to antiviral treatment.
Atara Biotherapeutics, Inc., the company developing ATA230, said it will evaluate development plans for this therapy with the FDA and other global health authorities after beginning phase 3 studies of another product, ATA129.
The company said it decided to prioritize ATA129, which is being developed to treat patients with Epstein-Barr-virus-associated post-transplant lymphoproliferative disorder.
Phase 2 trial of ATA230
Researchers reported phase 2 results with ATA230 at the 2016 ASH Annual Meeting.
The data encompassed 15 patients with documented CMV mutations conferring resistance to antiviral therapies. The patients had received a median of 3 prior therapies.
Eleven of the 15 patients (73.3%) responded to ATA230, 6 with complete responses and 5 with partial responses.
At 6 months, the overall survival was 72.7% in responders and 25% in non-responders.
Within the 6 months of follow-up, 1 of the 11 responders died of CMV, and 3 of the 4 non-responders died of CMV.
Adverse events occurred in 6 patients. One grade 3 event and 1 grade 4 event were considered possibly related to ATA230.
About orphan designation
The FDA grants orphan designation to products intended to treat, diagnose, or prevent diseases/disorders that affect fewer than 200,000 people in the US.
The designation provides incentives for sponsors to develop products for rare diseases. This may include tax credits toward the cost of clinical trials, prescription drug user fee waivers, and 7 years of market exclusivity if the product is approved.

FDA grants orphan designation to product for GVHD
The US Food and Drug Administration (FDA) has granted orphan drug designation to ApoGraft™ as prophylaxis for acute and chronic graft-versus-host disease (GVHD) in transplant recipients.
ApoGraft is a mobilized peripheral blood cell product collected via apheresis from a matched, related donor. The product is exposed to the apoptotic mediator Fas ligand prior to transplantation.
ApoGraft was designed to eliminate immune responses after transplantation of foreign cells and tissues.
ApoGraft is being developed by Cellect Biotechnology Ltd.
The company is testing ApoGraft as acute GVHD prophylaxis in a phase 1/2 trial.
The trial is currently enrolling patients with hemato-oncology disorders who are eligible for allogeneic, HLA-matched hematopoietic stem cell transplant (HSCT).
The study is expected to have 4 cohorts, each consisting of 3 patients.
The difference between the cohorts is the amount of apoptotic mediator Fas ligand (APO010) to which the graft is exposed during incubation prior to ApoGraft transplantation and HSCT:
- 10 ng/mL APO010 in Cohort 1
- 25 ng/mL APO010 in Cohort 2
- 50 ng/mL APO010 in Cohort 3
- 100 ng/mL APO010 in Cohort 4.
The study is expected to progress from one cohort to the next based on an independent data safety monitoring board review and analysis of safety data.

Withdrawn AML drug back on market in US
The US Food and Drug Administration (FDA) has approved use of gemtuzumab ozogamicin (GO, Mylotarg), a treatment that was initially approved by the agency in 2000 but later pulled from the US market.
GO is an antibody-drug conjugate that consists of the cytotoxic agent calicheamicin attached to a monoclonal antibody targeting CD33.
GO is now approved to treat adults with newly diagnosed, CD33-positive acute myeloid leukemia (AML) and patients age 2 and older with CD33-positive, relapsed or refractory AML.
GO can be given alone or in combination with daunorubicin and cytarabine.
The prescribing information for GO includes a boxed warning detailing the risk of hepatotoxicity, including veno-occlusive disease or sinusoidal obstruction syndrome, associated with GO.
GO originates from a collaboration between Pfizer and Celltech, now UCB. Pfizer has sole responsibility for all manufacturing, clinical development, and commercialization activities for this molecule.
Market withdrawal and subsequent trials
GO was originally approved under the FDA’s accelerated approval program in 2000 for use as a single agent in patients with CD33-positive AML who had experienced their first relapse and were 60 years of age or older.
In 2010, Pfizer voluntarily withdrew GO from the US market due to the results of a confirmatory phase 3 trial, SWOG S0106.
This trial showed there was no clinical benefit for patients who received GO plus daunorubicin and cytarabine over patients who received only daunorubicin and cytarabine.
In addition, the rate of fatal, treatment-related toxicity was significantly higher in the GO arm of the study.
Because of the unmet need for effective treatments in AML, investigators expressed an interest in evaluating different doses and schedules of GO.
These independent investigators, with Pfizer’s support, conducted clinical trials that yielded more information on the efficacy and safety of GO.
The trials—ALFA-0701, AML-19, and MyloFrance-1—supported the new approval of GO. Updated data from these trials are included in the prescribing information, which is available for download at www.mylotarg.com.

FDA reapproves gemtuzumab ozogamicin for CD33-positive AML treatment
The Food and Drug Administration has approved gemtuzumab ozogamicin (Mylotarg) for the treatment of newly diagnosed CD33-positive acute myeloid leukemia in adults, according to a press release.
Approval was based on results from three clinical trials. In the first, newly diagnosed AML patients who received gemtuzumab ozogamicin plus chemotherapy had significantly longer event-free survival than did patients who received chemotherapy alone. In a second trial, patients who received gemtuzumab ozogamicin alone had better overall survival compared to those who received only best supportive care. In the third clinical trial, 26% of patients who had experienced a relapse and received gemtuzumab ozogamicin experienced a remission.
Common side effects of gemtuzumab ozogamicin include fever, nausea, infection, vomiting, bleeding, thrombocytopenia, stomatitis, constipation, rash, headache, elevated liver function tests, and neutropenia; it is not recommended for women who are pregnant or breastfeeding.
Gemtuzumab ozogamicin was also approved to treat patients older than 2 years old who have experienced a relapse or have not responded to initial treatment.
“Mylotarg’s history underscores the importance of examining alternative dosing, scheduling, and administration of therapies for patients with cancer, especially in those who may be most vulnerable to the side effects of treatment,” Richard Pazdur, MD, director of the FDA’s Oncology Center of Excellence, said in the press release.

Nanocarriers could treat leukemia, lymphoma and improve HSCT
Researchers say they have created nanoparticles loaded with messenger RNA (mRNA) that can give cells the ability to fight cancers and other diseases.
To use these freeze-dried nanocarriers, the team added water and introduced the resulting mixture to cells.
The nanocarriers were able to target T cells and hematopoietic stem cells (HSCs), delivering mRNA directly to the cells and triggering short-term gene expression.
The T cells were then able to fight leukemia and lymphoma in vitro and in vivo. And the HSCs demonstrated improvements in growth and regenerative potential.
Matthias Stephan, MD, PhD, of Fred Hutchinson Cancer Research Center in Seattle, Washington, and his colleagues described this research in Nature Communications.
“We developed a nanocarrier that binds and condenses synthetic mRNA and protects it from degradation,” Dr Stephan said.
The researchers surrounded the nanocarrier with a negatively charged envelope with a targeting ligand attached to the surface so the carrier homes and binds to a particular cell type. When this happens, the cell engulfs the carrier, which can be loaded with different types of manmade mRNA.
The researchers mixed the freeze-dried nanocarriers with water and samples of cells. Within 4 hours, cells started showing signs that editing had taken effect.
The team noted that boosters can be given if needed. And the nanocarriers are made from a dissolving biomaterial, so they are removed from the body like other cell waste.
Testing the carriers
Dr Stephan and his colleagues tested their nanocarriers in 3 ways.
First, the researchers tested nanoparticles carrying a gene-editing tool to T cells that snipped out their natural T-cell receptors and was paired with genes encoding a chimeric antigen receptor (CAR).
The resulting CAR T cells maintained their ability to proliferate and successfully eliminated leukemia cells.
Next, the researchers tested nanocarriers targeted to CAR T cells and containing foxo1 mRNA. This prompted the T cells to develop into a type of memory cell with enhanced antitumor activity.
The team found these CAR T cells induced “substantial disease regression” and prolonged survival in a mouse model of B-cell lymphoma.
Finally, the researchers tested nanocarriers targeted to HSCs. The carriers were equipped with mRNA that “induced key regulators of self-renewal,” accelerating the growth and regenerative potential of the HSCs in vitro.
Future possibilities
Dr Stephan and his colleagues noted that these nanocarriers are built on existing technology and can be used by individuals without knowledge of nanotechnology. Therefore, the team hopes the nanocarriers will be an off-the-shelf way for cell-therapy engineers to develop new approaches to treat diseases.
The researchers believe the nanocarriers could replace electroporation, a multistep cell-manufacturing technique that requires specialized equipment and clean rooms. The team noted that up to 60 times more cells survive the introduction of the nanocarriers than survive electroporation.
“You can imagine taking the nanoparticles, injecting them into a patient, and then you don’t have to culture cells at all anymore,” Dr Stephan said.
He is now looking for commercial partners to move the technology toward additional applications and into clinical trials.

The researchers surrounded the nanocarrier with a negatively charged envelope with a targeting ligand attached to the surface so the carrier homes and binds to a particular cell type. When this happens, the cell engulfs the carrier, which can be loaded with different types of manmade mRNA.
The researchers mixed the freeze-dried nanocarriers with water and samples of cells. Within 4 hours, cells started showing signs that editing had taken effect.
The team noted that boosters can be given if needed. And the nanocarriers are made from a dissolving biomaterial, so they are removed from the body like other cell waste.
Testing the carriers
Dr Stephan and his colleagues tested their nanocarriers in 3 ways.
First, the researchers tested nanoparticles carrying a gene-editing tool to T cells that snipped out their natural T-cell receptors and was paired with genes encoding a chimeric antigen receptor (CAR).
The resulting CAR T cells maintained their ability to proliferate and successfully eliminated leukemia cells.
Next, the researchers tested nanocarriers targeted to CAR T cells and containing foxo1 mRNA. This prompted the T cells to develop into a type of memory cell with enhanced antitumor activity.
The team found these CAR T cells induced “substantial disease regression” and prolonged survival in a mouse model of B-cell lymphoma.
Finally, the researchers tested nanocarriers targeted to HSCs. The carriers were equipped with mRNA that “induced key regulators of self-renewal,” accelerating the growth and regenerative potential of the HSCs in vitro.
Future possibilities
Dr Stephan and his colleagues noted that these nanocarriers are built on existing technology and can be used by individuals without knowledge of nanotechnology. Therefore, the team hopes the nanocarriers will be an off-the-shelf way for cell-therapy engineers to develop new approaches to treat diseases.
The researchers believe the nanocarriers could replace electroporation, a multistep cell-manufacturing technique that requires specialized equipment and clean rooms. The team noted that up to 60 times more cells survive the introduction of the nanocarriers than survive electroporation.
“You can imagine taking the nanoparticles, injecting them into a patient, and then you don’t have to culture cells at all anymore,” Dr Stephan said.
He is now looking for commercial partners to move the technology toward additional applications and into clinical trials.
Researchers say they have created nanoparticles loaded with messenger RNA (mRNA) that can give cells the ability to fight cancers and other diseases.
To use these freeze-dried nanocarriers, the team added water and introduced the resulting mixture to cells.
The nanocarriers were able to target T cells and hematopoietic stem cells (HSCs), delivering mRNA directly to the cells and triggering short-term gene expression.
The T cells were then able to fight leukemia and lymphoma in vitro and in vivo. And the HSCs demonstrated improvements in growth and regenerative potential.

Young cancer patients want more digital support, survey says
A recent survey of young cancer patients in the UK revealed their desire for additional digital oncology resources.
The survey showed that many of the patients already used digital resources to access information about their cancer.
However, many also expressed a need for additional resources such as online counseling or psychological support.
Esha Abrol, of Camden and Islington NHS Foundation Trust in London, UK, and her colleagues reported these findings in the Journal of Cancer Survivorship.
The researchers surveyed 102 cancer patients, ages 13 to 24, about digital media use.
The patients reported having active digital lives, with 41.6% of them rating digital resources as “essential” to their lives.
The patients reported using a variety of healthcare-related digital resources to access information about their disease, including independent sources and ones recommended to them by the professional team treating them.
Half (51%) of respondents said they kept in contact through digital means with other patients they had met during treatment. Twelve percent contacted others or started new digital relationships with people they had never met in person.
However, most of the patients were still most likely to get information about their treatment from professionals in a face-to-face environment, such as when visiting their doctor.
“This is a reassuring and appropriate finding, as this is the conventional means by which teenage and young adult oncology care is delivered by the multidisciplinary team, whether the young people choose to engage or not,” Abrol said.
At the same time, many survey respondents expressed a desire for virtual online groups (54.3%), online counseling or psychological support (43.5%), and the ability to receive (66.3%) and share (48.9%) clinical information online.
Young adults (ages 19 to 24) were more interested than adolescents (ages 13 to 18) in online counseling options and preferred receiving clinical information online.
The researchers said this may reflect young adults’ greater independence, resilience, breadth of experience in the digital world, and confidence in discussing clinical matters online.
Abrol believes these preliminary results can help inform the development of local, national, and global services to teenagers and young adults with cancer to address their unmet needs.
“These digital support resources have the potential to improve patient experience and engagement for an important subsection of teenagers and young people treated for cancer,” Abrol said.

FDA approves first CAR T-cell therapy to treat ALL
The US Food and Drug Administration (FDA) has approved the first chimeric antigen receptor (CAR) T-cell therapy, tisagenlecleucel (KymriahTM, formerly CTL019).
The therapy is approved for use in children and young adults up to 25 years of age who have B-cell precursor acute lymphoblastic leukemia (ALL) that is refractory or in second or later relapse.
Tisagenlecleucel consists of autologous T cells expressing a CD19-specific CAR.
The therapy was first developed by the University of Pennsylvania. In 2012, the university and Novartis entered into a global collaboration to further research, develop, and commercialize CAR T-cell therapies. Novartis holds the worldwide rights to tisagenlecleucel and other therapies developed through the collaboration.
The application for tisagenlecleucel was supported by results from 3 clinical trials:
- A pilot study presented at the 2015 ASH Annual Meeting
- The phase 2 ENSIGN trial, which was presented at the 2016 ASH Annual Meeting
- The phase 2 ELIANA study, which was recently presented at the 22nd Congress of the European Hematology Association (EHA).
Safety concerns
The prescribing information for tisagenlecleucel includes a boxed warning noting that the treatment poses a risk of cytokine release syndrome (CRS) and neurological toxicity, both of which can be life-threatening.
Because of the risk of CRS, the FDA has expanded the approved use of tocilizumab (Actemra) to include treatment of CAR T-cell-induced severe or life-threatening CRS in patients age 2 and older.
The risk of CRS and neurological toxicity also prompted the FDA to approve tisagenlecleucel with a risk evaluation and mitigation strategy (REMS), which includes elements to assure safe use.
The FDA is requiring that hospitals and their associated clinics that dispense tisagenlecleucel be specially certified. As part of that certification, staff involved in the prescribing, dispensing, or administration of tisagenlecleucel are required to be trained to recognize and manage CRS and neurological events.
Additionally, the certified healthcare settings are required to have protocols in place to ensure that tisagenlecleucel is only given to patients after verifying that tocilizumab is available for immediate administration.
The REMS program specifies that patients be informed of the signs and symptoms of CRS and neurological toxicities following infusion and of the importance of promptly returning to the treatment site if they develop fever or other adverse reactions after receiving tisagenlecleucel.
To further evaluate the long-term safety of tisagenlecleucel, Novartis is required to conduct a post-marketing observational study involving patients who received the treatment.
Access and cost
Tisagenlecleucel will be manufactured for each individual patient at Novartis’s facility in Morris Plains, New Jersey.
Novartis said it has designed a manufacturing and supply chain platform that allows for an individualized treatment approach on a global scale. This process includes cryopreservation of a patient’s harvested cells, providing the flexibility to initiate treatment with tisagenlecleucel based on the individual patient’s condition.
Tisagenlecleucel will reportedly cost $475,000 for a single course of treatment. However, Novartis said it will help patients navigate insurance coverage and provide financial assistance for those who are uninsured or underinsured.
In addition, patients will only be required to pay for tisagenlecleucel if they respond within a month of receiving the treatment. This is a result of a collaboration between Novartis and the US Centers for Medicare and Medicaid Services that is focused on delivering value-based care. The approach is intended to include indication-based pricing for medicines and supports payments for a medicine based on the clinical outcomes achieved.

FDA approves drug to treat CRS induced by CAR T-cell therapy
The US Food and Drug Administration (FDA) has approved tocilizumab (Actemra®) for the treatment of patients age 2 and older who have severe or life-threatening cytokine release syndrome (CRS) induced by chimeric antigen receptor (CAR) T-cell therapy.
Tocilizumab is a humanized interleukin-6 receptor antagonist.
The drug is also FDA-approved to treat adults with rheumatoid arthritis or giant cell arteritis and patients age 2 and older with polyarticular juvenile idiopathic arthritis or systemic juvenile idiopathic arthritis.
The full prescribing information for tocilizumab, which includes a boxed warning about the risk of serious infections, is available at http://www.actemra.com. The drug is jointly developed by Genentech (a member of the Roche Group) and Chugai Pharmaceutical Co.
The FDA’s latest approval of tocilizumab coincided with the FDA’s approval of the CAR T-cell therapy tisagenlecleucel (Kymriah, formerly CTL019) to treat pediatric and young adult patients with relapsed or refractory B-cell precursor acute lymphoblastic leukemia.
According to Genentech, the FDA’s decision to expand the approval of tocilizumab is based on a retrospective analysis of pooled outcome data from clinical trials of CAR T-cell therapies in patients with hematologic malignancies.
For this analysis, researchers assessed 45 pediatric and adult patients treated with tocilizumab, with or without additional high-dose corticosteroids, for severe or life-threatening CRS.
Thirty-one patients (69%) achieved a response, defined as resolution of CRS within 14 days of the first dose of tocilizumab.
No more than 2 doses of tocilizumab were needed, and no drugs other than tocilizumab and corticosteroids were used for treatment.
No adverse reactions related to tocilizumab were reported.

FDA approves first gene therapy – tisagenlecleucel for ALL
The U.S. Food and Drug Administration has approved tisagenlecleucel (Kymriah), a first-of-its-kind chimeric antigen receptor T-cell (CAR T) therapy, for the treatment of children and young adults up to age 25 years with B-cell precursor acute lymphoblastic leukemia (ALL) that is refractory or in second or later relapse.
Tisagenlecleucel will carry a boxed warning regarding the CRS risk. Additionally, due to the CRS risk and risk of neurological events, the approval requires a risk evaluation and mitigation strategy (REMS), which includes elements to assure safe use, according to an FDA press release.
Special certification will be required for hospitals and associated clinics that dispense tisagenlecleucel. As part of certification, staff will be trained in the prescribing, dispensing, or administering of the therapy, and to recognize and manage CRS and neurological events.
Novartis, the maker of tisagenlecleucel, will be required to conduct postmarketing observational study.
Indeed, FDA commissioner Scott Gottlieb, MD, said the approval marks the entry to a “new frontier in medical innovation.”
“New technologies such as gene and cell therapies hold out the potential to transform medicine and create an inflection point in our ability to treat and even cure many intractable illnesses,” he said in the press statement.
Tisagenlecleucel is a genetically modified autologous T-cell immunotherapy involving customized treatment created using a patient’s own T cells. The T cells are genetically modified to include a chimeric antigen receptor that directs the T cells to target and kill leukemia cells with CD19 surface antigen, and are then infused back into the patient.
In a phase 2 clinical trial, the overall remission rate with tisagenlecleucel therapy was 83% in 63 children and young adults with relapsed/refractory B-cell precursor ALL for whom at least two prior lines of therapy had failed; the therapy was granted Fast Track, Priority Review, and Breakthrough Therapy designations.
“Kymriah is a first-of-its-kind treatment approach that fills an important unmet need for children and young adults with this serious disease,” Peter Marks, MD, director of the FDA’s Center for Biologics Evaluation and Research said in the press statement.
“Not only does Kymriah provide these patients with a new treatment option where very limited options existed, but a treatment option that shows promising remission and survival rates in clinical trials.”
At its meeting in July, the FDA ODAC agreed nearly unanimously that the risk mitigation plan put forward by Novartis, including planned 15-year follow-up and other mitigation measures, would be adequate for detecting serious consequences of CAR T-cell therapy.

In a phase 2 clinical trial, the overall remission rate with tisagenlecleucel therapy was 83% in 63 children and young adults with relapsed/refractory B-cell precursor ALL for whom at least two prior lines of therapy had failed; the therapy was granted Fast Track, Priority Review, and Breakthrough Therapy designations.
“Kymriah is a first-of-its-kind treatment approach that fills an important unmet need for children and young adults with this serious disease,” Peter Marks, MD, director of the FDA’s Center for Biologics Evaluation and Research said in the press statement.
“Not only does Kymriah provide these patients with a new treatment option where very limited options existed, but a treatment option that shows promising remission and survival rates in clinical trials.”
At its meeting in July, the FDA ODAC agreed nearly unanimously that the risk mitigation plan put forward by Novartis, including planned 15-year follow-up and other mitigation measures, would be adequate for detecting serious consequences of CAR T-cell therapy.
